2. Resistance thermometer - Wikipedia

   en.wikipedia.org/wiki/Resistance_thermometer

   Resistance thermometers are constructed in a number of forms and offer greater stability, accuracy and repeatability in some cases than thermocouples. While thermocouples use the Seebeck effect to generate a voltage, resistance thermometers use electrical resistance and require a power source to operate.

3. Callendar–Van Dusen equation - Wikipedia

   en.wikipedia.org/wiki/Callendar–Van_Dusen_equation

   The Callendar–Van Dusen equation is an equation that describes the relationship between resistance (R) and temperature (T) of platinum resistance thermometers (RTD).. As commonly used for commercial applications of RTD thermometers, the relationship between resistance and temperature is given by the following equations.

4. Medical thermometer - Wikipedia

   en.wikipedia.org/wiki/Medical_thermometer

   A medical thermometer or clinical thermometer is a device used for measuring the body temperature of a human or other animal. The tip of the thermometer is inserted into the mouth under the tongue (oral or sub-lingual temperature), under the armpit (axillary temperature), into the rectum via the anus (rectal temperature), into the ear (tympanic temperature), or on the forehead (temporal ...

5. Temperature measurement - Wikipedia

   en.wikipedia.org/wiki/Temperature_measurement

   Resistance temperature detector (RTD) Pyrometer; Langmuir probes (for electron temperature of a plasma) Infrared thermometer; Other thermometers; One must be careful when measuring temperature to ensure that the measuring instrument (thermometer, thermocouple, etc.) is really the same temperature as the material that is being measured.

6. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury ...

7. Photothermal microspectroscopy - Wikipedia

   en.wikipedia.org/wiki/Photothermal_microspectroscopy

   The resultant measured temperature fluctuations provide an interferogram that replaces the interferogram obtained by a conventional FTIR setup, e.g., by direct detection of the radiation transmitted by a sample. The temperature profile can be made sharp by modulating the excitation beam.
